To al whom it may concern e it known that I, Gnsriiv A. BADER, a citizenof the United States, and resident of Rochester, in the county of Monroeand State of New York, have invented certain new and useful ImprovementsinEyeglass- Mountings, of which the following is aspecification. Thisinvention relates to eye-glass mountings of the type in whichnose-engaging members orclamps are carried byarms or levers projectingrearwardly from the plane of the lenses, and the object of the inventionis to provide nose-clamp lovers of novel andimproved form, wherein thesheet-metal of which they are constructed is so shaped, and' has itswidth so disposed, as to provide with greater facility for bending thelevers, at various points, toadjust the position of the nose-clamps inaccordance with the peculiarities of the person to whom the glasses areto be fitted. i

To the foregoing! end I employ, in my novel nose-clamp lever an inte ralsheetmetal member shaped and bent in sucha manner as to provide twosubstantially U- shaped portions, of which the first, lying adjacent thepivotal support of the lever,

' has vertical arms in which the width of the sheet-metal lies inparallel planes extending transversely with respect to theeyeglassmounting as a Whole, while thesecond U- shaped portion springsfrom one of the vertical edges of the rear arm of the first U- shapedmember, and has two arms lying in a substantially horizontal plane, andwith 'the width of the sheet-metal vertical.

In the accompanying drawings: Figure 1 is a plan-view, on a greatlyenlarged scale, of one-half of an eyeglass mounting embodying thepresent invention and; Fig. 2 is a perspective view, on a still largerscale, of the nose-clamp lever shown in Fig. 1.

The invention is illustratedas embodied in an eyeglass mounting havingthe usual rigid bridge 5, which is connected with each lens 6 by meansof the usual lens-clip 7 The end-portion of the bridge is provided withthe usual vertical pivot 8, upon which the nose-clamp lever has itsbearlng.

The nose-clamp lever is formed of sheet metal, which is cut to asuitable pattern and then bent to shape. It has a flat portion 9 inwhich the sheet-metal lies horizontally, this portion being perforatedto receive the Specification of Letters Patent.

pivot 8, and being adapted to lie and turn against the upper surface ofthe bridge; The leverhas a forwardly projecting eX- tremity orfinger-piece'lO, by which it may be operated in the usual manneri [Thenovel form and construction of the lever is embodied in itsrearwardly-projecting arm or portion by which ported. part 9-of thelever themetal is bent upwardly and then downwardly, so as to form a.vertically disposed U-shaped part having forward and rear arms '11 and12, respectively, in which the metal lies in planes transverse tothelength of the lever. From therear arm 12 of the U-shaped portion. justdescribed the metal then extends directly from one of the verticaledgesof the.

the nose-clamp is sup- At a point near to the pivotal arm, and is bentinto the form of a second L -shaped portion disposed horizontally andhaving arms 14 and 15, in which also the sheet-metal lies in planestransverse to the length of the lever. The rearmost arm 15 serves as asu pport for the nosesclamp. 16.

T 1e arm 15 is connectedpivotally with the nose-clamp 16 by means of apivot 29'which passes through the arm and through a lug 17 onthenose-clamp. v

The form of the nose-clamp lever above described is such that it lendsitself readily to the various adjustments required in devices of'thekind in question. The horizontally disposed U-shaped portion is adaptedto have its arms bent toward or from each other, so as to adjust theeffective length of the lever, while they may also be twisted slightlyto changethe rearward inclination of the nose-clamps. The height of thenoseclampsmay be readily adjusted by bending the lever at the verticallydisposed U-shaped portion. The width of the sheet-metal in the variousparts of the lever lies in planes which render these adjustments easyand tend. to confine the bending to the points where it is mosteffective.

In addition to the advantages just pointed out, the novel form ofthenose-clamp lever has the-further advantage that the vertical U-shapedportion provides a pocket or recess 13 adapted to receive the end of thenoseclamp spring. This spring, as illustrated in Fig. l, is of the usualform, having a coiled portion'20 which surrounds the pivot-stud 8. I

which is bent so that it may enter the recess 13. In this manner thespring is connected with the lever, and at the same time the extremity21 is substantially concealed, and is effectually protected againstcatching in the the inward swinging movement of the noseclamp and thelever.

1..In an eyeglass-mounting, the combination, with a bridge, andnose-clamps located in the rear. of the bridge, of nose-clamp leversformed integrally of sheet-metal and each comprising a part pivoted tothe bridge on a substantially vertical axis, a U-shaped part locatedclose to the rear of the bridge and in front of the correspondingnoseclamp and having substantially vertical arms in which the width ofthe metal is transverse to the length of the lever so that the arms maybe twisted about vertical axes to cause the rear ends of the levers tobe swung toward or from each other, and a part extending rearwardly froma vertical edge of the rear arm of the U-shaped part and carrying thenoseclamp at its rear end, the

width of the sheet-metal in said part being vertical so that said partmay be bent to correct the change in the angular position of Copies ofthis patentmay be obtained for five cents each, by addressing theCommissioner of Patents,

the nose-clamp resulting from the twisting of the Ushaped part.

In an eye glass-mounting, the combination, with a bridge andnose-clamps located in the rear of the bridge, of noseclamp leversformed integrally of sheetmetal and each comprising a part pivoted tothe bridge on a substantially vertical axis, a U-shaped part locatedclose to the rear of the bridge and in front of the correspondingnose-clamp and having substantially vertical arms in which the width ofthemetal is transverse to the length of the lever, so

that the arms may be twisted about vertical axes to cause the rear endsof the levers to be swung toward orfrom; each other, and a partextending rearwardly from a vertical edge of the rear arm of theU-shaped part GUSTAV A. BADER.
